Pharmacy

Does anyone bill for Pharmacy services?  We have a PharmD (Doctor of Pharmacy) on staff and are trying to figure out how she can bill for MTMS (Medication Therapy Management Services).  We have been told by MN DHS (MA) that we can bill the codes related to this service.  The issue I am having now is that some of the clients also have Medicare.  We can only bill for Medicare Part B.  With her degree this would fall under Medicare Part D, which we are not able to enroll in because we do not have a pharmacy onsite. 

Any help would be much appreciated.

Thanks!
